Due to the RP2350 datasheet errata E9 we decided not to test, qualify, FCC/CE test a new revision 5XL. 5XL will be available again if there is a new RP2350A that fixes the E9 errata and can be used with the existing certified design. Bus Pirate 6 with a fix for E9 is available. Follow ian in the Bus Pirate forum for live updates.
Bus Pirate 5XL (RP2350A) with enclosure. 520K ram, 2x ARM M33 cores, 2x RISCV Hazard 3 cores. With enclosure, alternate button caps, and hex wrench.
